本發明係有關於一種電源供應裝置，尤指一種具有低待機功耗的電源供應裝置。The present invention relates to a power supply device, and more particularly to a power supply device having low standby power consumption.
配合參閱第一圖，為習知之電源供應裝置之電路方塊圖。電源供應裝置1連接於一交流電源供應器ACP及一電子系統PS，電源供應裝置1接收交流電源供應器ACP輸出的交流電力，並將交流電力進行電能轉換後傳遞至電子系統PS。電源供應裝置1可供操作在正常模式或待機模式(standby mode)，其中正常模式操作是指電源供應裝置1必須提供電子系統PS操作時所需的電力，意即在正常模式時，連接於電源供應裝置1的電子系統PS處於開機狀態；反之，待機狀態是指電子系統PS處於關機狀態。Referring to the first figure, it is a circuit block diagram of a conventional power supply device. The power supply device 1 is connected to an AC power supply ACP and an electronic system PS. The power supply device 1 receives the AC power output by the AC power supply ACP, and converts the AC power to the electronic system PS. The power supply device 1 is operable to operate in a normal mode or a standby mode, wherein the normal mode operation means that the power supply device 1 must provide power required for the operation of the electronic system PS, that is, in the normal mode, connected to the power source. The electronic system PS of the supply device 1 is in a power-on state; otherwise, the standby state means that the electronic system PS is in a power-off state.

電源供應裝置1接收交流電源供應器ACP輸出的交流電力。在交流電力輸入電源供應裝置1後，電磁干擾濾波器10先濾除交流電力中的電磁干擾，整流器11用以將電磁干擾濾波器10所輸出的交流電力轉換為直流電力輸出。在整流器11中可以加入功率因素校正(Power Factor Correction)電路110，以降低輸入電流量。
The power supply device 1 receives the AC power output from the AC power supply ACP. After the AC power is input to the power supply device 1, the electromagnetic interference filter 10 first filters out electromagnetic interference in the AC power, and the rectifier 11 converts the AC power output from the electromagnetic interference filter 10 into a DC power output. A Power Factor Correction circuit 110 can be added to the rectifier 11 to reduce the amount of input current.
主電源轉換器12接收整流器11輸出的直流電力，主電源轉換器12接受第一控制器14控制，以改變第一電源輸出端VA及一第二電源輸出端VB輸出之電力。主電源轉換器12為直流/直流轉換器(DC to DC converter)，並可例如為LLC諧振式電源轉換器、雙重順向式電源轉換器(Dual Forward Converter)或單一順向式電源轉換器(Single Forward Converter)。附屬電源轉換器13接收整流器11輸出的直流電力，附屬電源轉換器13接受第二控制器15控制，以改變輸出之電力。附屬電源轉換器13可例如為返馳式轉換器(flyback converter)。
The main power converter 12 receives the DC power output from the rectifier 11, and the main power converter 12 is controlled by the first controller 14 to change the power outputted by the first power output VA and a second power output VB. The main power converter 12 is a DC to DC converter and can be, for example, an LLC resonant power converter, a dual forward power converter, or a single forward power converter ( Single Forward Converter). The auxiliary power converter 13 receives the DC power output from the rectifier 11, and the auxiliary power converter 13 is controlled by the second controller 15 to change the output power. The accessory power converter 13 can be, for example, a flyback converter.
主電源轉換器12在正常模式時進行電能轉換以使直流電力轉換為主電力並由第一電源輸出端VA及第二電源輸出端VB輸出，並在待機模式時停止電能轉換並不輸出主電力(意即第一電源輸出端VA及第二電源輸出端VB不輸出電力)。附屬電源轉換器13不論在正常模式或待機模式時均進行電能轉換以使直流電壓轉換為待機電力並由待機電源輸出端Vsb輸出。電源供應裝置1藉由在待機模式時，停止主電源轉換器12輸出電力，可以有效地降低電源轉換裝置1在待機模式的能源消耗，以達到省電的目的。
The main power converter 12 performs power conversion in the normal mode to convert the direct current power into the main power and is output by the first power output terminal VA and the second power output terminal VB, and stops the power conversion in the standby mode and does not output the main power. (meaning that the first power output terminal VA and the second power output terminal VB do not output power). The auxiliary power converter 13 performs electric energy conversion in the normal mode or the standby mode to convert the direct current voltage into standby power and is outputted from the standby power output terminal Vsb. When the power supply device 1 stops the output power of the main power converter 12 in the standby mode, the power consumption of the power conversion device 1 in the standby mode can be effectively reduced to achieve power saving.
然而，電源供應裝置1必須同時包含主電源轉換器12及附屬電源轉換器13，這使得電源供應裝置1的體積大，並且，在正常模式操作下，主電源轉換器12及附屬電源轉換器13必須同時進行電能轉換，導致電源供應裝置1在正常模式操作下的能源消耗增加。
However, the power supply device 1 must include both the main power converter 12 and the auxiliary power converter 13, which makes the power supply device 1 bulky, and, in the normal mode operation, the main power converter 12 and the auxiliary power converter 13 The power conversion must be performed at the same time, resulting in an increase in energy consumption of the power supply device 1 under normal mode operation.
